MOTOR.

SPECIFICATION forming part of Letters Patent No.-e03,173, dated April26, 1898 Application filed August 9, 1897.

T0 at whom it may concern:

Be it known'that I, HENRY CLAY,'a citizen of the United States, residingat Fernwood, in the county of Delaware, State of Pennsylvania, haveinvented a new anduseful Improvement'in Motors, which improvement isfully set forth in the following specification and accompanyingdrawings.

My invention consists of a novel assemblage of mechanism whereby I amenabled toconvert a maximum speed with a minimum power into a maximumpower with a minimum speed, the novel features of the invention beinghereinafter-fully set forth, and

particularly pointed out in the claims.

Figure 1 represents a diagrammatic plan view of a motor embodying myinvention. Fig. 2 represents a horizontal sectional view through theupper'portion of Fig. 1, showing the relation of the cylinders, valves,ports,-

sponding parts'in the several figures.

Referring to the drawings, A designates the main shaft of an electric orother high-speed.

motor or other initial source of power, the same having a worm B mountedthereon, which is adapted tomesh with the gear 0, the gear'beingisecuredto the shaft D, which rotates in suitable bearings.

E designates a-series 0f eccentrics or cams which are mounted on theshaft D, the work-- ing faces of which cams engage the adjacent yokes F,the 'endsG of which are attached to the plungers or pistons H,- whichare caused to reciprocate in their cylinders J, there betion of onesetjwill suffice for all, reference being therefore had to the left ofFigs. 1 and 3.

- K designates a pipe leading from the end Serial No. 647,517. (Nomodel.)

of the cylinder J to the compartment S of thevalve-chest L.

M designates a suction-pipe for each of the valve-chests, the same beingconnected with the pipe N, which communicates with the reservoir P,which is filled with glycerin, oil, or other suitable fluid.

Q designates the suction-chamber of the valve-chest L, the same having'aport leading therefrom into the compartmentS, said port being controlledby a check-valve R, which in the present instance seats downwardly, asindicated at the left of Fig. 3.

U designates the discharge-chamber of the valve-chest L, the same havinga port leading thereto from the compartment S, said port beingcontrolled by the downwardlyseating check-valve T.

V designates the discharge-pipes, which lead from each of thedischarge-chambers U, thev same being connected and finally discharginginto the pipe W, which leads to the reversing-valve X,said valveconsisting of a casing X, in'which the plug X is' rotatably mounted,said plug being-held in position by the ring X3 and having the passage Xextending therethrough, by means of which communicationis had with thepipe Y, which is connected with the pipe Z, which latter leads to; thepoints A B. The valve-plug X has aport X passing therethrough at anangle to the port X and when'the'ports are in the position seen in Fig.5 said port X communicates'with'the pipes X and X X and X designatepassages or ports in the valve-plug X which are arranged substantiallyparalleltothe port X X designates a suitablehandl'e wherebythe'valve-plug X is manipulated.

, The rotation of the shaft A, by reason of the intermediateconnections, will cause the reciprocation of the plungers' or pistons'11, thereby effecting a continuous flow of liquid from the reservoir Pthrough the pipe N to the port 0, past the neck 0 of the valve b,

.lmil

into the port D, against the piston E, contained in the cylinder F,thereby forcing said piston forward or to the right and effecting therotation of the shaft J by means of the connecting-rod common to saidpiston and to the crank II of said shaft, the piston L, contained in thecylinder M, simultaneously moving to the right by reason of theconnection of the connecting-rod K thereto. The piston E moves forwardlyuntil the full stroke is made, at which point the port (1 is uncovered,into which the liquid flows against the valve b, thus forcing the sameto the left and closing the passage between the ports C and D, the neckC being 110w opposite the port (Z which is thus opened. As the valve Z)moves to the left the fluid in the chamber 6 is forced through the pipe0 around to the chamber 0, against the end of the valve 1), thus forcingthe latter to the left, the port (1 being then closed and the port (Zopen, since the neck b is now opposite said latter port. The piston L isnow occupying a position at the extreme right of its cylinder M and isin proximity to the port N, which leads to the ports (1" and (Z at whichpoint the bridge M allows a communication between the ports M and pipeM'flwhereby the liquid is permitted to escape from the chamber 0 to saidpipe M and thence through the pipe M to the pipe M and back to thereservoir P. \Vhen the piston L moves from the position seen in Fig. 2to the right, it forces the fluid in the chamber M through the ports Nand d to the port P, the fluid being exhausted thence into the pipe P,thence to the pipe X, and, through the port of the valve X to the pipe Xto the reservoir.

The operation above described takes place in the cylinders F M and adetailed description thereof is therefore deemed to be unnecessary, thefluid in the pipe 6 which serves the same function for its valve-chestsas the pipe c moving back and forth alternately in the directionindicated in full and dotted arrows.

To reverse the motor, the valve-plug X is turned into the positionindicated in Fig. 6, the fluid passing in at pipe TV, through the port Xto and out pipe X, to the pipe P", and then to the valve-chests in thedirection indicated by dotted arrows, the exhaust taking place throughthe pipe Y, port X and pipe X back to the reservoir.

The speed is controlled by the throttlevalves II the maximum power beingobtained from the shaft J when said valve II is closed, the opening ofthe valve II furnishing a by-pass for a portion of the fluid passingthrough the pipe V, and .thus reducing the volume and pressure throughthe pipe Y, thereby reducing the power applied to the shaft J, fromwhich latter it is of course understood that power may be transmitted toany desired point.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
